Observation Of The Appearance And Function Of Nasal Mucosa And After Functional Endoscopic Sinus Surgery

Objective: Observation of the appearance and function of nasal mucosa in chronicrhinosinusitis with nasal polyps(CRSwNP) and chronic rhinosinusitis without nasalpolyps(CRSsNP) after functional endoscopic sinus surgery（FESS）.Method： The morphological character of nasal mucosa after FESS was surveyedcontinuously with endoseopy in59cases with CRSwNP and CRSsNP.Result: There were89.8%of nasal and sinuous cavity became clean1～2week aftersurgery. There were81.4%of nasal and sinuous cavity grew partial vesicles,granulation and small polyps3～12week after surgery. There were76.3%of nasaland sinuous cavity brought to stage of complete epithelization12week after surgery.Conclusions: Three stages were divided after FESS. They are stage of clean operativecavity, stage of mucous competition and stage of complete epithelization. Propertreatment and the strict postoperative follow-up system to restore the nasal mucosaplays an important role.
